If you do a lot of body work these air punch-flangers will save you a ton of time. Sure Eastwood sells manual flangers that produce a similar effect with just your own brute strength, but using them for large jobs can take up a lot of time and energy. Why not use the power of compressed air to get the job done faster? Speed through the flanging part of the job, and spend more time on the welding and body work that actually shows. These tools also will punch holes in sheet metal which makes tack welding door skins and such a breeze too.
We've also got a flanger-crimper attachment that works with your pneumatic hammer to produce the same results, without having to pay for a whole other air tool. Perfect for the occasional DIYer.
